The fuel pump circuit is protected by a 20 amp «EFI Main» fuse. It is enabled via a relay named «C/OPN Relay«. Strangely, Toyota has never referred to a fuel pump relay as a «fuel pump relay«. Always «C/OPN«. Do you know why? I do not.
The fuel pump motor is grounded through the white and black wire, power is supplied through the red wire.
